Benchmark 9C: The Mathematical World - Shapes

• Length can be thought of as unit lengths joined together, area as a collection of unit squares, and volume as a set of unit cubes. (1 of 6)
• Standard 10-1 page 51, Grades K-4
Understand the attributes of length, capacity, weight, area, volume, time, temperature, and angle

Standard 12-5, page 112, Grades 5-8
Understand and apply geometric properties and relationships

• If 0 and 1 are located on a line, any other number can be depicted as a position on the line. (2 of 6)
• Standard 9-4 page 48, Grades K-4
Relate geometric ideas to number and measurement ideas

Standard 5-5, page 87, Grades 5-8
Represent numerical relationships in one- and two-dimensional graphs

• Graphical display of numbers may make it possible to spot patterns that are not otherwise obvious, such as comparative size or trends. (3 of 6)
• Standard 11-2 page 54, Grades K-4
Construct, read, and interpret displays of data
• Many objects can be described in terms of simple plane figures and solids. Shapes can be compared in terms of concepts such as parallel and perpendicular, congruence, similarity, and symmetry. Symmetry can be found by reflection, turns, or slides. (4 of 6)
